Chifeng roller (www.chifeng123.cn) Co., Ltd. specializes in producing all kinds of custom roller, product quality is guaranteed! I produced parallel into parallel and parallel to the lower idler roller. Parallel roller conveyor for carrying items into that side support for carrying, the scope HKG pier, mining transportation or some mechanical equipment; parallel under the roller conveyor support for the return trip, which is used to support the load side Scope of application to prevent the belt deviation. Model specifications can contact us special order! Works idler roller drive roller tube, bearing and bearing outer ring by friction between the conveyor and the roller, seals rotary motion, and transfer conveyor and to achieve together with its logistics. Front idler roller 1. use and operation use should be carefully examined whether the appearance of serious damage bump phenomenon, rotating roller should be flexible rotation, no jamming. 2. idler mounting distance should be considered the type and characteristics of volume size conveyor logistics scientific computing may be, to avoid too sparse or too dense installation. 3. The installation should be adapted roller mill to avoid touching each other. Roller classification 1, according to material into rubber roller, ceramic roller, nylon roller and insulating roller. 2, the main trough idlers, various parallel roller group, various types of self-aligning roller group, various buffer roller group. (1) trough roller common type roller, roller-type forward, quick roller bearing type, hanging type roller, three chain roller, roller reversible, variable-angle trough idlers, transitional roller, V-type roller, etc; (2) a common type of parallel rollers roller, comb-type roller, forward-type roller, steel rubber roller type, screw-type roller, etc; (3) self-aligning There are universal roller friction roller reversible, strong type roller, tapered roller, screw-type roller, roller, etc. Combined; (4) buffer roller spring plate roller, roller-type cushion ring, strong buffer type roller, roller adjustable elastic type, hanging type roller, etc; factors affecting the quality of the idler roller radial runout 1. (a direct impact on the stability of the index of the material transport) 2. Axis to string momentum (directly affect the life of idlers) 3. flexibility (lifetime effects roller life and tapes, as well as the whole drive power) 4. Waterproof (impact idler life) 5. Anti- dust properties (impact idler life) 6. axial load carrying capacity (impact idler life) 7. impact resistance (impact idler life) 8. rotational resistance (affects the life of the tape) maintenance and repair of idlers 1. Roller 20000h above normal life, usually without maintenance. However, according to the use of premises and load size, should develop appropriate service date, timely cleaning oiling maintenance, clean the float coal. For abnormal sounds and do not turn the roller should be replaced. 2. Replace the bearings, bearing cage must open outward, into the roller bearing, it should maintain proper clearance, not crushed. 3. labyrinth seals should be used original parts, respectively, should be loaded into the roller assembly, the assembly shall be set together. 4. Use the roller, should prevent heavy blow to hit the roller tube. 5. In order to ensure sealing rollers and performance, is prohibited disassemble roller
